Portal will be available on Google Play for NVIDIA Shield starting May 12

Pick up this classic PC game for $9.99 and get the best experience playing with a controller on Shield.

Portal has been winning awards from critics and praise from gamers since its first introduction in 2007, and the game is finally going mobile with a launch on the NVIDIA Shield. Following up after an announcement of the game for the Shield at GTC in March, Portal will be available to play in all its glory starting May 12th for $9.99.

Leveraging Valve's Source engine, Portal plays as an exact replica of the PC and console game on the NVIDIA Shield, with perfect support for the controller and landscape-only screen. Considering what this game requires in terms of resources it plays surprisingly well on the Shield, although I have to say there's a little bit of tweaking to do in the settings to make things just right. Graphics look good and best of all the controller input works flawlessly — from joysticks to buttons and triggers — and the mapping is customizable within the game.

Portal is a great purchase at $9.99 for anyone that wants to take a trip down memory lane and replay a great game while on the move with a Shield, and will also be a great choice for anyone that is looking for a true PC-level game on their mobile device. Going beyond this single title it marks a huge step in gaming possibilities now that NVIDIA and Valve have the Source engine running on Android, and we can only imagine what that holds in terms of future releases.

If you're okay with the price, you won't be disappointed by what's on offer with Portal loaded on the Shield. Unfortunately you'll have to wait a few days until May 12th for the game to be live for everyone in the Play Store, but we can assure you it's worth the wait.

This is the kind of thing we need to see more of. More actual AAA game ports. I expect to see HL1 and 2 and L4D games in the near future since they run on the same engine. I would buy a shield for better exclusive games like this.

Indeed. The game isn't at all ready for touch, so it'd actually require a game controller, but that would be pretty crazy. Honestly not sure if the Note 3 has enough horsepower to play this game, though. It's clearly pushing the Shield to its limits, and that has some ridiculous CPU and GPU power.

CPU in Tegra 4 is a little bit powerful than CPU in Snapdragon 800. About GPU...well, games are running on tegra 4(not only Shield. Xiaomi Mi3, for example) not worse and sometimes better than on Snapdragon 800.
About this game — it's seems to be Source Engine, and I hope it really is.

I'd love to see more PC ports on Android.Look, if Borderlands 2 can be done on the Vita, why not also make one for Android? I know the original Shield is an order of magnitude more powerful than the Vita, so it's at least technically feasible.
